The IEEE Transactions on Haptics seeks articles for a 2012 special issue on Haptic Human-Robot Interaction. Touch is an inevitable component of interaction in collaborative environments. Haptic human-robot interaction is still largely underrepresented compared to other fields of interaction research such as communication via speech and gestures. Safe and intuitive haptic human-robot interactions will be essential for future robotic systems that interact directly with humans, assist them in performing physical tasks, enhance motor training and rehabilitation, and even interact socially such as shaking hands and dancing. The Guest Editors invite papers addressing all aspects of haptic human-human and human-robot interaction. Potential authors should also note that the first tournament for handshake algorithms and handshake classification will be held in June, 2011 as part of a workshop funded by the Israel Science Foundation at Ben-Gurion University of the Negev. Participants will be encouraged to submit papers to the Special Issue to report their findings, describe the rationale behind their algorithms, and interpret their results. Articles are due by 15 September 2011. Visit http://www.computer.org/toh to view the complete call for papers and submission instructions.
